Just an FYI for anyone putting together a tiki event on a budget: solid-color inflatable balls from Dollar Tree work great as ad hoc glass floats for a party.

We had some LED puck lights from a past event that were simple to hide in the top rope (with a layer of electrical tape to block any other light leakage). They illuminate through the ball for fantastic ambience.

You can follow Batjakknots to weave the rope, or just improvise with cuts of cheap netting/simple knots like I did, it all ends up capturing the effect pretty well for ~$3 per light
